Mary Johnston

Lower School Director

A product of Walsingham herself, Mrs. Johnston spent the first four years of her professional career teaching in Georgia before returning to her alma mater where she has spent the last 30 years both as a teacher and now an administrator. Her mother also spent over thirty years as an educator at Walsingham starting in 1964 as one of the first lay-faculty members at the school.

Mrs. Johnston sees education as being first and foremost founded within an environment of care and respect.The process of teaching will only work if the teacher is able to communicate with the compassion and joy that builds community. Students must feel welcome, valued, and loved for a classroom to be a place of learning.She sees her role as a Mercy educator as being a walking example of the Mercy core values; for students to see the values modeled every day and gain a deep understanding of Mercy education that they will then be able to use to bring change to their future work environments, homes, and communities.
